Africa Bags. It's a nonprofit started by a woman named Holly Petitt and her husband that is dedicated to providing the people in Malawi the skills necessary to make reusable bags, purses and backpacks. The canvas totes run as little as $7.00, and absolutely all of the profits go back to Malawi (there are currently seven villages participating).
One really cool thing about Africa Bags is that each bag is signed by the village that made it on the inside edge, and you can look up each village on the website to find out more about it and what the money raised is helping do. The organization also offers ways to get involved with micro-lending (think Kiva).
